Step-by-step explanation:
<u>Step 1: Define</u>
f(x, y) = 2x - 3y + xy²
(3, -1) is x =3 and y = -1
<u>Step 2: Evaluate</u>
- Substitute: f(3, -1) = 2(3) - 3(-1) + 3(-1)²
- Exponents: f(3, -1) = 2(3) - 3(-1) + 3(1)
- Multiply: f(3, -1) = 6 + 3 + 3
- Add: f(3, -1) = 9 + 3
- Add: f(3, -1) = 12

t = V+K/g, n=multiply both side by g to get :
TG = V+K
now divide both sides by T to get G alone
so G = V/t + K/t = g = (V+K)/t

The horizontally compress the exponential function f(x)=2^x by a factor of 3 is f(3x)=2^3x
When we compress a function y=f(x) by a scale factor of 'k', where k >1, then the function after compression will become :
y=f(x), where k>1
We have given the Exponential function.
<h3>What is the scale factor?</h3>
The scale factor is a measure for similar figures, that look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
The scale factor of the compression (k): 5
Then after horizontal compression, the exponential function will become
f(3x)=2^3x

Okay so, the first thing you need to do is find the total number of students. 46 divided by 2 (you get the 2 from 2/3) is 23 (which is a weird number) Now you multiply 23 by 3, which is 69.
